FIELD OF THE INVENTION

The present invention relates to an air-powered gun, in particular to the air-powered gun with an air-storage extension tube.

BACKGROUND OF THE INVENTION

Nowadays, most people pursue leisure activities for refreshment and excitement, and thus air-powered gun has become one of the popular outdoor activities for the training of shooting, exercise and team work. The air-powered gun generally uses a high-pressure gas as power source, and liquid carbon dioxide stored in a steel cylinder is set in contact with room temperature of the outside environment, so that the state of carbon dioxide is changed from a liquid state to a gas state to provide motive power for firing the gun.

The aforementioned air-powered gun has a barrel and an air chamber interconnected with each other, and the steel cylinder is installed to the air-powered gun and a switch valve is provided and can be opened to introduce the gaseous carbon dioxide into the air chamber. When the pressure accumulated inside the air chamber is greater than atmospheric pressure, the gaseous carbon dioxide is discharged from the barrel.

However, after the switch valve of the air-powered gun is opened, carbon dioxide enters into the air chamber directly, so that the vaporization path is very short. If a part of the carbon dioxide still not vaporized completely (which is still in the liquid state) is entered into the air chamber and discharged from the barrel for the firing, the firing force will be insufficient and the performance of using the steel cylinder will be lowered.

In view of the aforementioned problems, the inventor of the present invention based on years of experience in the related industry to conduct researches and experiments, and finally provided the present invention to overcome the problems of the prior art.

SUMMARY OF THE INVENTION

Therefore, it is a primary objective of the present invention to provide an air-powered gun with an air-storage extension tube that stores liquid carbon dioxide contained in a steel cylinder into an air-storage extension tube before the liquid carbon dioxide enters into an air chamber, so as to achieve the effects of extending the vaporization time, increasing the firing force of the air-powered gun, and improving the performance of using the steel cylinder.

To achieve the aforementioned objective, the present invention provides an air-powered gun with an air-storage extension tube, comprising: a gun body; an air inlet module, including an air chamber and a switch valve, and the air chamber being disposed inside the gun body and having an inlet, and the switch valve being installed corresponding to the inlet; a trigger, pivotally coupled to the gun body; a hammer, coupled to the gun body and linked with the trigger, and capable of pressing at or detaching from the switch valve; a pressurized bottle chamber, formed at the gun body; and an air-storage extension tube, fixed to the gun body, and having an end interconnected to the inlet and the other end interconnected to the pressurized bottle chamber, and the air-storage extension tube being disposed between the trigger and the hammer, and having at least one turn.

The present invention has the following effects:

The liquid carbon dioxide in the steel cylinder is entered and stored into the air-storage extension tube first. Since the total length of the air-storage extension tube is greater than 3 centimeters, the vaporization time is extended to achieve the effects of improving the using efficiency of the steel cylinder and the firing impact force of the air-powered gun.

In addition, the air-storage extension tube includes a space formed between the trigger and the hammer and at least one turn. In other words, the air-storage extension tube is installed at a part of the external periphery of the hammer and the trigger to increase the total length of the air-storage extension tube in the limited space, so as to prevent an increase of volume of the air-powered gun and improve the vaporization efficiency of the steel cylinder.

In addition, the air-powered gun further comprises a blocking element to give the feel of a real gun, so that the hammer has a flip member formed thereon and provided for users to flip, but the blocking element and the hammer are abutted against each other, such that a space is formed between the hammer and the switch valve. Even if the flip member is stricken, a bullet will not be shot, so as to improve the safety of using the air-powered gun of the present invention.
